About
This is a single-center, open-label, randomized, three-period, six-sequence study to evaluate the effect of food (high-fat and low-fat) on the PK of HMPL-523. In this study, 18 healthy Chinese participants are planned to be enrolled, randomized in a ratio of 1:1:1:1:1:1 to one of 6 dosing sequences (see dosing sequence table for details), and administered once per cycle for 3 cycles, with a washout period of at least 7 days. The study consists of a screening/baseline period, a dosing period (three cycles), and a follow-up period.
Full description
Screening Period/Baseline Period The trial participants will sign a written informed consent form on a voluntary basis prior to screening. Screening period/baseline period assessment will be completed within 14 days prior to the first dose. At screening/baseline, demographic data, medical history, medication history, allergy history, blood donation history, and participation in clinical trials should be collected, and physical examination, vital sign measurements, 12-lead ECG, infection markers, laboratory tests, pregnancy test , and chest X-ray will be performed.
Trial participants who pass the preliminary screening will be admitted to the study site 3 days prior to the first dose (i.e., 3 days prior to medication of Cycle 1), vital signs examination, urine drug abuse screening, alcohol breath screening will be performed on the day of admission, recent dietary and medication use will be inquired, and pregnancy test will be conducted (only for women of childbearing potential. If the screening examinations and baseline examinations will be conducted on the same day, they can be done once), and the inclusion and exclusion criteria will be further checked.
Only serious adverse events will be collected during screening/baseline period. Dosing Period (3 cycles) The day before the first administration, trial participants passing the screening will be given a randomization number according to the randomization scheme, and assigned to one of 6 dosing sequences in a ratio of 1:1:1:1:1:1. The dosing sequences include ABC, ACB, BAC, BCA, CAB and CBA, and the three dietary conditions are fasting (A), standard high-fat breakfast (B) and standard low-fat breakfast (C). Each participant will receive a single oral dose of HMPL-523 acetate tablets 300 mg (3 tablets × 100 mg) on Day 1 of each cycle in accordance with the dosing sequence. During the study, every effort should be made to ensure that the participant takes the medication according to the study protocol.
Administration Method Fasting (A): Participants will fast for at least 10 hours, have blank blood sample collected, and take the study drug with about 240 mL of water. Except for the water for drug administration mentioned above, water will be deprived from 1 hour pre-dose and 1 hour post-dose. Food will be deprived within 4 hours post-dose.
Standard high-fat breakfast (B) or standard low-fat breakfast (C): Participants will fast for at least 10 hours before the standard high-fat breakfast (B) or standard low-fat breakfast (C), start eating breakfast 30 minutes before dosing, and finish the meal within 25 minutes. After the meal, participants will have blank blood sample collected, and take the study drug with about 240 mL of water exactly 30 minutes from the start of the meal. Water will be deprived from 1 hour pre-dose to 1 hour post-dose, except for the beverages included in the prescribed breakfast and water taken with medication. Food will be deprived within 4 hours post-dose.
During hospitalization, the diet of the participants will be provided by the site. On the day of dosing in each cycle, lunch and dinner (both regular meals) will be served 4 hours and 10 hours after dosing, respectively; at other times, 3 meals will be provided according to the schedule arranged by the site.
The dosing period consists of three cycles, and the scheduled PK blood sampling time points for each participant in each cycle are as follows: within 0.5 hours pre-dose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 12, 24, 36, 48, 60,and 72 hours post-dose, with a total of 18 collections, and about 3 mL of venous blood will be collected each time. The 4-hour post-dose blood sample must be taken prior to lunch.
After the participants are admitted to the clinical study ward, the vital sign measurements will be performed 1 day pre-dose in each cycle and 3±1 hours post-dose on Day 1 of each cycle. Vital sign measurements, blood chemistry, and hematology will be performed on Day 4 of the each of Cycle 1 and Cycle 2. On Cycle 3 Day 4, the participants will be discharged after vital sign measurements, physical examination, laboratory tests, and 12-lead ECG examination are completed.
Strenuous exercise, alcohol, tobacco, tea, and caffeinated beverages should be avoided during the study. Seville oranges, grapefruits or beverages containing these fruits should be avoided during the study.
Follow-up Period Participants will be followed up to Day 12±2 after the last dose (the day of the last dose is defined as Day 1 of follow-up period). The investigator will collect all (adverse events) AEs and concomitant medications/therapies from the participants during this period through telephone calls (or other means such as text messages). If there are AEs ongoing at follow-up, follow-up will continue until the events return to normal level, abnormal and not clinically significant, baseline level, stable or lost to follow-up, or refusal to visit, etc.
